A narrated walk-through of this site: the ramp, the gaps, the surfaces, and the hazards, read from the survey.
Read the transcript
From the intersection of MT 206 and Highway 2, travel east for 2.1 miles. Turn left on the gravel drive immediately after the Glacier Ziplines property.
The parking area is packed dirt.
There is no designated accessible parking.
The Flathead Rivers Alliance has not published measured survey data for this site yet, so the details that follow come from the site description rather than from field measurements.
The launch itself is vehicle accessible bar packed dirt, pebble bar.
What to watch for, in the survey crew's own words:
Launch washes out at high water, making put-ins and take-outs dynamic and challenging.
Site is often extremely muddy after periods of rain.
There are no facilities at this site.
This site has not been photographed in 360 yet, so there is no immersive imagery to accompany this description.
Conditions on the Three Forks change quickly. Check the gauge the morning you float.

The site
This undeveloped access approximately 1 R.M. downstream from the confluence for the main Flathead River is used by recreators floating the lower miles of the Wild and Scenic Middle Fork or the undesignated stretch of the South Fork below the Hungry Horse Dam. A steep and heavily used gravel road makes multiple switchbacks down to an eroded beach launch.
